Fluoride in aquatic systems is increasing due to anthropogenic pollution, but little is known about how this fluoride affects organisms that live in and around aquatic habitats. Fluoride can bioaccumulate in structures comprised of calcium carbonate,

Laser-induced desorption coupled with Fourier transform mass spectrometry (FTMS) has proven to be a useful technique for the studies of chemical reactions that occur in monolayers adsorbed on solid surfaces. The high sensitivity and ultrahigh mass re

Current doctrine states that phosphorus is incorporated into cells in the pentavalent(V) oxidation state as orthophosphate. However, recent studies show that microorganisms contain enzymes used to metabolize reduced forms of phosphorous, including ph

Pyridine adsorption on NiAl(100) and ultrathin films of γ-Al 2 O 3 was studied using high-resolution electron energy loss spectroscopy (HREELS). Pyridine adsorbs on NiAl(100) with its molecular axis parallel to the surface plane at low coverages and

Ultrathin films of γ-Al2O3 grown on NiAl(001) were studied using high-resolution electron energy loss spectroscopy (HREELS), Auger electron spectroscopy (AES), and low-energy electron diffraction (LEED). Growth of the ultrathin oxide films with wate

Highly crystalline thin films of gold were grown on scratch-free mica. Epitaxial growth was accomplished by heating a fleshly cleaved 8 mm×8 mm piece of mica to 380 °C for 12 h at 1.9×10−7 Torr, followed by gold deposition at 1 A/s and 380 °C u

Historically, it was assumed that reactive, inorganic phosphorus present in pristine environments was solely in the form of orthophosphate. However, this assumption contradicts theories of biogenesis and the observed metabolic behavior of select micr

We have developed a new interface for a commercial ion trap mass spectrometer equipped with APCI capable of real-time measurements of gaseous compounds with limits of detection on the order of pptv. The new interface has been tested using the detecti

We describe here the dimerization of 1,3-butadiene to form 4-vinyl-cyclohexene on highly ordered hydroxylated ultrathin films of γ-Al2O3. High surface area, powdered γ-Al2O3 is widely used as a catalyst and catalyst support. In addition, there is i
